Topping cannabis plants is one my favourite plant training methods. This method allows us to create multiple semi-identical flowering shoots, while making the plant wider and efficient for indoor grow lights. Learning this technique will open the door to growing monster plants with huge yields.
It all begins when the plants are small. You simply take away the new shoot from the centre of another 2 shoots. This causes the 2 outside shoots to grow pretty much identical. When done properly, a short, wide, symmetrical plant can be grown allowing you to fill the width of your grow room with less plants. So if your looking to grow a 20 ounce plant below your 600 watt light, topping cannabis is the first method you could do with learning.
